When wild-dunking, shot-blocking forward Chris Andersen disappeared from the NBA in 2006 because he tested positive for banned substances, NBA fans surely believed they'd seen the last of the man they called "Birdman." But after two years of banishment, Andersen returned to the league, and last off-season, he wound up back in Denver. Heavily tattooed, overly gelled and apparently substance-free, he's won back the hearts of Nuggets fan with his steady if sometimes spastic play, logging an average of six rebounds, six points and two blocks per game, and filling in a Nuggets puzzle that's close to complete.
